Biological filter is the core equipment of aquaculture. In the case that the total water in the circulating water is fixed, but the total amount of nitrogen input is constantly increasing, under the action of organisms, these nitrogenous substances would be converted into ammonia or nitrite dissolved in water. The continuous accumulation of these substances will cause the organisms poisoning. Therefore, these nitrogenous substances must be converted into non-toxic substances in aquaculture.
Biological filter tank(Biochemical tank) is a kind of biological filter container, its delicate design keeps the water flow within a certain range and ensures that the biofilm can be attached to the biofilter
material as soon as possible, so as to exert the best effect together with the whole system.
Sand filter, protein skimmer, air pump or fan
Biological filter tank(Biochemical tank) is not recommended to used with the ozone generator, but can be preinstalled with UV sterilizer.
Non-toxic food grade PP or PVC
WL-BFG bead filter is closed pressure filter, not only designed with nice and modern appearance, but also minimize the size of filtration system compare to the traditional one. The installation and operation is very simple, and function is very complete. It provides mechanical filtration and biological filtration at a single unit, with bobbin-wound fiberglass reinforced tank, 6-way multiport valve, piping, circulation pump, air blower, control box and base.
When the water flows through the filter tank, large particles will be trapped by the filter media, small particles will be also blocked by the linked filter media. After certain time, these particles will be accumulated and the pressure inside the tank will increase, then the filter can be backwashed to clear the accumulated particles and release the tank pressure.
By breeding beneficial bacteria inside the filtration media in the filter tank, the beneficial bacteria can convert into non-toxic substances and digested.
